BURAS, LA - JULY 05: Danene Birtell (L) and Melanie Reed clean oil off of a laughing gull at the Fort Jackson Oiled Wildlife Rehabilitation Center July 5, 2010 in Buras, Louisiana. The center has handled about 700 birds that were contaminated by oil from the Deepwater Horizon drilling rig after it exploded on April 20, leaking millions of gallons of oil into the Gulf of Mexico.
